Problems solved by technology

[0003] The research in the field of high magnetic permeability has shifted from the simple pursuit of high magnetic permeability to the improvement of comprehensive performance. To ensure its own high magnetic permeability in different environments, other dopants are generally added in the preparation process to ensure its own practicability, but the overall performance is not good, and it is difficult to ensure comprehensive adaptation effects such as high operating temperature and environmental loss. Therefore, We propose a wide-temperature high-permeability soft ferrite material and its component preparation method

Abstract

The invention discloses a wide-temperature high-permeability soft magnetic ferrite material and an element preparation method thereof. The wide-temperature high-permeability soft magnetic ferrite material comprises a main material and an auxiliary material. The main material accounts for more than or equal to 99.50% by mass, and the auxiliary materials accounts for less than or equal to 0.5%. The main material comprises the following components in percentage by mass: 50.5%-52.5% of ferric oxide, 24.5%-26.5% of manganese oxide; and 22%-24% of zinc oxide. The auxiliary material comprises calcium carbonate, copper oxide, bismuth trioxide, silicon dioxide, tin oxide, niobium pentoxide, titanium dioxide, cobalt sesquioxide, molybdenum trioxide and tungsten dioxide. The auxiliary material is added, the total amount of the auxiliary material is controlled to be 0.5% or below, and the magnetic flux density of the ferrite material is enhanced through matching of the auxiliary material, so that the environmental adaptability is improved, the problem that the loss is too large when the ferrite material is used in a severe environment is solved, and the comprehensive performance of the wide-temperature-range high-permeability soft magnetic ferrite material is improved.

Description

technical field [0001] The invention belongs to the technical field of new materials, and more specifically relates to a soft ferrite material with wide temperature and high magnetic permeability; at the same time, the invention also relates to a method for preparing a soft ferrite element with wide temperature and high magnetic permeability. Background technique [0002] When the magnetic permeability of the material is high, the required inductance can be obtained with fewer coil turns, thereby effectively reducing the DC resistance of the coil and the loss caused by it; secondly, the use of materials with high magnetic permeability can significantly reduce the inductance. The small size of the transformer is conducive to the miniaturization and weight reduction of devices and systems. These characteristics conform to the development trend of electronic products, and its output has accounted for more than 25% of the total output of all soft ferrites. With the rapid develo...
